Designing Physical Unclonable Functions From Optically Active Materials

open access: yesAdvanced Materials, EarlyView.
Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

Bio‐Inspired Artificial Muscle‐Tendon Complex of Liquid Crystal Elastomer for Bidirectional Afferent‐Efferent Signaling

open access: yesAdvanced Materials, EarlyView.
The Muscle–tendon complex (MTC)‐inspired Liquid crystal elastomer (LCE) artificial muscle integrates actuation (efferent) and proprioceptive sensing (afferent) by combining contractile nematic and elastic isotropic LCEs within a single soft structure. Embedded liquid metal channels enable simultaneous Joule heating and real‐time sensing of length and ...

Self‐Spiking Linear Neuromorphic Soft Pressure Sensor for Underwater Sensing Applications

open access: yesAdvanced Materials, EarlyView.
This study presents a novel design of a neuromorphic pressure sensor that can generate self‐spiking symmetric signals with direct event‐based encoding through the integration of magnetic spheres and alternating coil circuits. The key advantages of this work include high linearity up to 200 kPa (R2 = 0.997), self‐spiking behavior for simplified signal ...

Néel Tensor Torque in Polycrystalline Antiferromagnets

open access: yesAdvanced Materials, EarlyView.
This work introduces a Néel tensor torque based on a rank‐two symmetric tensor capturing spin correlations in a polycrystalline antiferromagnet. It shows the Néel tensor can be shaped and reshaped through the spin‐orbit torque (SOT) technique, enabling field‐free SOT switching with a specific polarity of the adjacent ferromagnet. This discovery opens a
